-To all whom it may concern.-

Be it known that I, CAnLE'roN ELLIs, a citizen of the United States, residing at Roslindale, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Paint and Varnish Removers, of which the following is a specification.

The object of this invention is to produce an improved paint and varnish remover which, owing to the presence of the paint and varnish solvent, methyl acetone, containing about forty per cent. acetone, some methyl (wood) a cohol, and the balance higher ketones, is, as ,I have found by experinish remover containing acetone-free alcohol as asolvent of some paints and varnishes. The pungent odor of acetone (CH COCH is commercially objectionable in paint and varnish removers if any very large quantity of acetone be used-therein, and this objectionable pungenc of odor is overcome if a mixture of methy acetone containing about forty per cent. acetone, some meth l acetone, and the balance higher ketonesis used for the wax precipitant or gelatinizer in the paint and varnish remover.

In accordance with my present invention I take a suitable quantity of any suitable wax or waxy body and dissolve it in any suitable solvent. Among the Waxes suitable for use are paraflin, ceresin, and carnauba. Among the wax solvents suitable for use are benzole, benzin, and gasolene. Numerous other suitable waxes or waxy bodies and numerous other suitable Wax solvents Well known to those skilledin the art maybe used, if preferred, and these may be mixed in any suitable manner to produce the waxy solution.

Havin obtained by mixingthe wax solvents an waxy bodies in any suitable manner the desired waxy solution, I add thereto an alcoholic body, which is called in trade methyl acetone and contains about forty per cent. acetone, some methyl-that is, wood lcohol, andthe balance higher ke-fi tones. By the use of said methyl acetone as a gelatinizer a paint and varnish remover is produced at a cost less than would be required if alcohol were used, and cheapness of ingredients is a matter of great importance in said removers.

In some cases it may be preferred to use a quantity of methyl (Wood) alcohol and a separate quantity of acetone instead ,of

methyl acetone in mixture with the required wax and wax solvent, de ending on the market rates for acetone, w ich varies considerably in price from time to time.

The proportions of the ingredients that I have found satisfactory are for a'liquid remover as follows: benzole, one hundred gallons; methyl acetone, ninety-five gallons; wax, twenty pounds. For liquid -removers I also find the following proportions satisfactory: benzole, one hundred gallons; methyl acetone, eighty gallons; wax, teen to twenty pounds.

The proportions that I have found'satisfactory for a pasty remover are the same as the above with the addition of about forty pounds of wax in each case. i

The proportions stated may be varied within widelimits andyield a substantially non-evaporating paint and varnish remover. The in edients may be mixed in any order, accord to the convenience of the maker. The liqmds and wax may -be shaken up to- %ether until dissolved, and this is facilitated yheating.

A paint and varnish remover made in accordance with this invention is substantially neutral in its action on wood, hands, and brushes and acts practically only on the finish which is being removed, and this is an important advantage.

I am the first so far as I know to use methy acetone in paint and varnish removers as a gelatinizer. I

WhatI claim is- 1., As a new article of manufacture, a substantially neutral paint .and varnish remover com rising a wax; a solvent for the wax; and a ge atinizer containingabout forty per cent.

acetone, some methyl alcohol and the haling methyl acetone; other paint and varnish ance higher ketones. Solvents a, Wax; and awax solvent.
